Question

我通过django表单向我的Django Rest Framework api提交POST请求。

以下是我的表单片段：

<form action="{% url 'entry-list' %}" method="POST" class="form" role="form">
{% csrf_token %}

{{form.as_p}}
<div class = "form-group">
    <button type="submit" class="save btn btn-default btn-block">Save</button>
</div>

views.py ：

class entry_ViewSet(viewsets.ModelViewSet):
    queryset = Entry.objects.all()
    serializer_class= EntrySerializer
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,IsOwnerOrReadOnly,)
    def perform_create(self, serializer):
        serializer.partial = True
        serializer.save(created_by=self.request.user)

我正在成功发布POST（并且项目是在数据库中创建的），但是一旦我保存，我会转到显示我的api w / Markdown的网址/api/entry/。我想让它回到一个特定的网址。

有没有办法自定义POST重定向到哪里成功？

添加了Serializer：

class EntrySerializer(serializers.ModelSerializer):

    created_by = serializers.ReadOnlyField(source='created_by.username')
    class Meta:
        model = Entry
        fields = '__all__'
    def __init__(self, *args, **kwargs):
        super(EntrySerializer, self).__init__(*args, **kwargs)        
        for x in self.fields:
            self.fields[x].required = False

viewsets.ModelViewSet有一个返回Response对象的方法create。响应对象是Django Response的子类型。因此，您可以使用HttpResponseRedirect将行为更改为create方法。例如：

class entry_ViewSet(viewsets.ModelViewSet):
    queryset = Entry.objects.all()
    serializer_class= EntrySerializer
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,IsOwnerOrReadOnly,)

    def create(self, request, *args, **kwargs):
        response = super(entry_ViewSet, self).create(request, *args, **kwargs)
        # here may be placed additional operations for
        # extracting id of the object and using reverse()
        return HttpResponseRedirect(redirect_to='https://google.com')

    def perform_create(self, serializer):
        serializer.partial = True
        serializer.save(created_by=self.request.user)

在POST django休息框架后重定向
